The present invention relates to a swing being provided on each of saidrails, one particularly for small children and has for adjacent eachend. The hangers are provided its primary object to provide, in a mannerwith out-turned, headed upper end portions as hereinafter set forth, adevice of this charwhich are journaled in the rails 2.

Referring now to the drawings in detail, A sectional pitman which isdesignated genit will be seen that the combination of the orally by thereference numeral 18 operainvention which has been illustrated comtivelyconnects the upper end of each bell prises a supporting structure whichis desigcrank 16 to the lower end of a lever 12 for acnated generally bythe reference numeral 1, tuation thereby.

In use, as will be apparent,the body may be caused to swing back andforth by the occupant thereof by simply rasping and shifting the handlebar 14, thereby swinging the levers 12. the pitmans 18 and the bellcrank levers 16 to the rear hanger 5.

he coil portions of the bell cranksimpart resiliency to said bell cranksso that when the body is swinging too violently the bell cranks throughtheir resiliency will act as shock absorbers andresist theswingingmovement and thus cause the swing or device to work smoothlyback and forth. The, spring forming portions of the pitmen 18 also actas shock absorbers and tion of the device.
